Cube Visualisation Test

Sixty questions about cubes whose faces carry colours or simple shapes, in three parts of twenty with eight minutes each: turning the cube as arrows show, working out hidden faces from several views, and deciding which picture shows the same cube in a new position. Each part starts with an explanation and a worked example. Click the picture you choose.

The questions get harder within each part. A wrong answer costs nothing, so answer every question, guessing if you have to. Your score is the number right in each part and in all.

These are new items, generated and checked by computer, with no data yet: your answers help calibrate them.
